Step 1

Step 2

First we need to extract our textures and meshes for the item we want to convert using Sims 4 Studio.

Once you find the item you want, select it.

NOTE:If you want to have all of the colors for an item select all the color variations of the object, using Shift+Click. (as pictured below) This way all the color swatches will show up so you can extract them.

After you have everything you want, click "Next".

Save this .package file to your Desktop, as "Base Mesh".

That way we know this is the file we are starting from.

Next extract all of your Textures, under the "Texture Tab".

Extract all of the following to your desktop.

You will need:

All of the Diffuse textures for each swatch (if you have more than one swatch color.)

Specular

Normal

Next we need to get the mesh from "LOD 0", under the "Meshes" tab.

Extract "LOD 0" to your desktop.

If you have all of your textures and your mesh, you can close that Sims 4 Studio window.

Step 3

Next we need the Teen - Elder item we are cloning from.

Open a new window of Sims 4 Studio.

Select "Create 3D Mesh" again, and click "CAS".

Find an item that is similar to the mesh you are converting.

(You do not need to select all color types this time, just one.)

Since I am converting a baseball cap, I am going to use another type of ball cap. (as pictured below)

The reason we are selecting a hat that has a similar shape (or sits the same on the head) is to avoid having to make a new hat chop. (aka how the hair functions with a hat on.)

Once you have your clone, click "Next".

Save this .package to your mods folder.

Location: Documents > Electronic Arts > The Sims 4 > Mods

Step 4

Go to the "Meshes" tab, and extract "LOD 0" from your clone.

Save the mesh to your desktop as "Clone".

Once you have the Clone mesh on your desktop, minimize Sims 4 studio.

We will be coming back to it in a few. (Do not close the window).

Step 5

Find your "Clone" mesh on your desktop, and open it with Blender.

Select the mesh of your accessory until it is hilighted. (as pictured below).

Now that we have our mesh selected, we need to append the mesh we are converting.

Go to: File > Append

Select Desktop if it is not visible, then select your mesh on the desktop.

Once you click on the mesh, you will see a list of items.

Click on the "Object" folder.

Select all of the items named "s4studio_mesh". These are all the parts to your mesh.

In this tutorial I only have one to work with.

Now we should have our new mesh visible in the same file with our clone.

Next you need to move, resize, and make any changes to the new mesh you are wanting.

Do not delete the old mesh, grab and move it out of the way.

So it is no longer sitting in the same spot that our new mesh is going. (Not overlapping)

We will be using it later.

Blender mini tutorial Here. (coming soon)

Useful Hotkeys for Beginners:

G = Grab (move the mesh around)

G+Z = Move up and down

G+X = Move side to side

G+Y = Move front to back

R = Resize

R+(Z,X,Y) = resize up down, side to side, front to back

Once you have your mesh to your liking:

Select the new mesh until it is hilighted

Hold Shift, then select the clone mesh.

(Must be selected in that order.)

Now that you have both items selected press, CTRL+J to join them together.

Now both meshes should be joined together and selected in orange.

If you are unsure they joined, you can move the mesh and both parts will move. (as pictured below)

NOTE:By joining the mesh this way, we do not have to worry about cut numbers or bone assignments, But if your mesh has more that one cut, or is on a different body part than the item you are cloning from, you will have to change these.

Now that we have out meshes joined, we need to get rid of the old mesh.

Click "Object Mode" under your model window, and change it to "Edit Mode.

Once you are in "Edit Mode" you will now see a wire frame of your mesh and the old mesh.

If anything is selected and hilighted, unselect it by pressing "A"

Next click "C" to pull up circle select. Select all of the old mesh.

Next press "X or Delete" and delete the old mesh that you selected. (as pictured below)

Now that the old mesh is gone, all we have left is our new mesh.

Once you are happy with it. Save your new .blend.

File > Save as > Save to desktop > Named "New Mesh".

Step 5

Open up the Sims 4 Studio window with the clone that we had earlier.

Navigate to the "Meshes" Tab

Import your new mesh you just saved into "LOD 0".

Wait until it's done processing, once done. Go to the "Textures" window.
